Novel technique for fault location estimation on parallel transmission lines using wavelet

초록

In this paper, the novel technique for fault location has been investigated on parallel transmission lines using wavelet. Using this technique, we propose two parts for accurate, rapid fault detection and fault location estimation regardless of mutual coupling between parallel lines. The first part is fault detection and extraction of the fundamental signal using wavelet transform. The second part is fault location estimation using least square error method independent of fault resistance, and the remote in feed, etc. The results of extensive simulation showed that it successfully protected the parallel transmission line compared to the traditional techniques more quickly and reliably.
